About Wildtype

Wildtype is on a mission to create the cleanest, most sustainable seafood on the planet, starting with sushi-grade salmon. We’re pioneering cellular agriculture to protect wild species and our oceans, and to reverse trends of global food insecurity. Wildtype will provide consumers with a new option for real seafood that provides the same nutritional benefits as the most pristine wild-caught fish, without common contaminants such as mercury, microplastics, antibiotics, or pesticides.

We were founded in 2016 by Aryé Elfenbein, a cardiologist and molecular biologist, and Justin Kolbeck (CEO), a former US diplomat who served in Pakistan and Afghanistan, in an effort to solve one of the world’s biggest problems: how to feed a growing population without stripping the earth of its natural resources and biodiversity. Investors include L Catterton, Jeff Bezos, Spark Capital, CRV, Temasek, Leonardo DiCaprio, and Robert Downey Jr.’s Footprint Coalition, among others. 

Come join us in transforming our food system for good!

What you will own at Wildtype

  • Improving new and existing approaches to novel cell line development across species, with regards to yield optimization, and suspension growth
  • Establishment and optimization of new and high-throughput methods to increase phenotypic diversity of our cells and select for better performing strains
  • Perform characterization of in-house cell lines using cell & molecular approaches
  • Validate results of cell line development through culture of in-house cell lines in adherent, suspension, and benchtop bioreactor cultures
  • Be an essential part and key independent contributor to a nimble cell biology team
  • Learn and grow with Wildtype as we push cell lines forward, and make your mark on the future of our company

What you bring to the table

  • Ph.D. in Cell/Molecular biology, Biochemistry, or Biomedical Sciences with 3+ years of experience with cell culture
  • 1+ years mammalian cell culture experience, exposure to stem, insect, or fish cell lines a plus
  • Exposure to primary, aquatic, and/or stem cells preferred
  • Ability to execute high-throughput cell line optimization, with a focus on phenotypic outputs and strain selection
  • Expertise with novel/primary cell line development, suspension cultures, and non-targeted mutagenesis & selection is greatly preferred
  • Signaling biology, cell metabolism, cell cycle biology background is a plus
  • Ability to work independently with respect to experiment planning, design, execution, optimization, data analysis, interpretation, and communication
  • Careful and considerate approach that produces unassailable data with the ability to plan next steps & contingencies, effectively
  • Skillful communication, highly attentive to detail and diligent note keeping
  • Innovative problem solving, that does not rely on established methods and standard operating procedures

What we’ll teach you

  • Our current process for cell line development and suspension culture
  • How to grow and thrive in a fast-paced startup environment
  • How we pull together to overcome challenges in the face of audacious goals


Impact Plan

  • Within 1 month you will have adapted your background in cell biology and cell line development to Wildtype’s unique context. You will have set your professional development goals for the next 12 months.
  • Within 3 months you will have full ownership of cell line development project(s) that are directly related to company-wide goals. You will work alongside your mentor to plan novel approaches and draft a quarter-long experimental approach to achieving key biological objectives. You will be comfortable with our standard approaches and begin formulating new ideas.
  • Within 6 months your scientific contributions will have produced a deeper understanding of the nature of our cells, as well as several new strains that look to improve upon our current standard. You will have expanded your understanding of cell line development to improve an expanded roster of biological frontiers.
  • Within 12 months you will have deeply characterized and validated at bench top scale, several new strains across species. You will have produced a strong foundation upon which cell line development of new and existing strains are best handled. You will help to mentor junior members of the team, and interface across teams to facilitate technology transfers. Your inputs will help shape goals within cell line development as well as the greater cell biology team.
